We have AEM6.2 node environment and we are trying to access login.html but getting error as below.
After searching I came to know that java version could be one of the possible reason but I am already using Java 8 for this application. I am out of ideas. Any suggestions greatly appreciated.

Thank you.
General solution for errors are thrown by servlets compiled from jsp files, is to recompile the jsp again.
Goto system/console and verify if all bundles are in active state
Goto sling --> jsp and recompile all jsps.
This works if errors are thrown from otb jsp. However when custom application jsps throw error, you ll need to fix the custom jsp code by handling the error.
Another foolproof way to clear cached jsp class files is to delete /var/classes
The stacktrace indicates the NPE is stemming from defaulttopnav_jsp.java, line 347. Analysing the generated java file is the way to go.
Since AEM 6.1, the default ClassLoader was replaced by FSClassLoader and the generated .java files are no longer stored under /var/classes.
To locate the .java file you will need to locate the bundle ID for the FSClassLoader bundle, then the java files will be located at:
[AEM_INSTALL_DIR]/crx-quickstart/launchpad/felix/bundle[BUNDLE_ID]/data/classes
There is also a sling plugin which will help you view the generated java file from OSGi console. Check out these posts for that.

I am learning to solve some optimisation programs using google or-tools.
I started with their example code and I an trying to run it in intellij.
But when I write the code and compile I get the following error.

I searched for some answers and I found that it requires jniortools.dll .
But I am working with ubuntu. Hence i assume i need to load the libjniortools.so file , am I right?.
So I included the line
static {
System.loadLibrary("libjniortools");
}
and I have a lib folder wherein I have put both com.google.ortools.jar and protobuf.jar along with all the other lib files that were present when I extracted the zip file(basically copy pasted the lib folder from extracted zip file).
I have added the jar paths in intellij as shown in figure
enter image description here
*the last 2 line of dependency in image
Then I have also tried giving the lib path in VM-options:
-Djava.library.path=/home/surajvashistha/IdeaProjects/LPModel/lib
After all this, I get the following error
Exception in thread "main" java.lang.UnsatisfiedLinkError: no libjniortools in java.library.path

I am stuck here and not able to move forward. Can anyone help?
I downloaded the OfBiz Java application and the following line throws an MissingResourceException:
ResourceBundle res = ResourceBundle.getBundle(settingsResourceName);
The value of settingsResourceName is "cache", but I cannot find any file called cache.properties or cache_en.properties.
Where should I be looking? I'm new to Java. All my research on SO says there should be such a file.
I imported OfBiz in Eclipse using the Import menu option and selecting Existing Project from File System (I'm not in front of my dev machine so I don't remember the exact wording). But I chose the root folder of the downloaded OfBiz.
I then added the appropriate VM Arguments in the Run Configuration to get it to run properly at least. And that's it, on the first Run I got the above error. I think it has to do with a missing class path but I don't know what to add to class path.
Here is the stack trace:

UPDATE:
My mistake, I found two files both called cache.properties in the following folders:
ofbiz-trunk/build/resources/main
ofbiz-trunk/framework/base/config
But these are folders, not packages. I tried putting them in the .classpath but that did not work, I still kept getting the same error.
As suspected, I knew it was because of a missing reference to a class path. After looking at a section on this page: http://www.opensourcestrategies.com/ofbiz/ofbiz_eclipse.php, I learned that I was supposed to go to the Java Build Path and in the Libraries tab, click on Add Class Folder, then point that to ofbiz-trunk/framework/base/config. Which is where I have one of the cache.properties files.

I've been struggling to properly integrate this Netflix Java Client to access Netflix's API into a very basic Eclipse Java Web Project.
Whenever I try to publish any content referring to this library, I get errors like the following, indicating an inability to resolve the type of the classes in the external library I'm trying to use.
Aug 20, 2011 11:48:42 AM org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet [jsp] in context with path [/OSNet03] threw exception [Unable to compile class for JSP:
An error occurred at line: 19 in the jsp file: /index.jsp
NetflixAPIClient cannot be resolved to a type
16: String myConsumerKey = new String("cefjbgekg7566cqrp2atua2n");
17: String myConsumerSecret = new String("redacted");
18:
19: NetflixAPIClient apiClient = new NetflixAPIClient(myConsumerKey, myConsumerSecret);
20: String uri = APIEndpoints.MOVIE_URI + "/2361637";
21: String details = null;
At the top of the file I include the proper class directories like this:
<%# page import="com.netflix.api.*" %>
<%# page import="com.netflix.api.client.*" %>
<%# page import="com.netflix.api.client.dal.*" %>
And I don't receive any errors from Eclipse telling me it can't resolve the classes. Only once I publish it to the server does this error occur.
I've tried building with jre7 and jdk1.7.0. The library I'm trying to work with includes elements that are from Java v6 and v5.
I included the library by building it with Maven and placing the directory in my WEB-INF/lib folder and then including the jar netflix-client-2.3-SNAPSHOT.jar in my Build Path.
I've looked all over the web for possible causes and tried every prescribed solution I've found but none have worked.
You may be able to tell I'm very new to using Eclipse and Java Web Programming but I'm trying to figure things out as best I can as I go.
check if build automatically is on :P. if not try turning it on for once.
if yes then check the project build path and look for libraries. check if the correct jars are there.
also check if your jars are not corrupted.
these are the usual problems for more wait for sm1 else to answer.
you could also try searching for the resource class that can't be resolved using Ctrl+Shift+R and see if the class turns up.
if you don't get it, then just extract the jar and see if the class is there for real.
We're currently creating an app that needs ATG taglibs on SLING/OSGI, we have created a bundle with these taglibs and uploaded it, of course these taglibs call ATG classes, so we are including them in the bootdelegation, using sling.properties file.
sling.bootdelegation.simple=atg.nucleus
sling.bootdelegation.class.atg.nucleus.Nucleus=atg.appassembly, \
atg.appassembly.ant, \
atg.appassembly.progress, \
atg.appassembly.util, \
...ETC...
First we got this error:

So we added atg.taglib.dspjsp to the packages to be added in bootdelegation sling.properties file.
Then we got this error:

All this is running on JBOSS.
Is there a way to avoid this class conflict that is causing the cast exception?
The class cast exception is usually a sign that that class is being made available in two different places (in your case probably via bootdelegation and maybe via a bundle that exports this class). That's what I would investigate first.
Also, to make things more explicit, I would in general advise you to not use boot delegation but instead export these packages explicitly through the system bundle. That way at least you can better debug where classes come from and how things are "wired" by the OSGi resolver.
When loading the ATG tag libraries from outside of the OSGi framework you also have to make sure to provide the JSP API from outside of the framework. By default Sling embeds the JSP API (in the JSP Scripting Bundle).
There are various ways to expose the JSP API into the framework. One is to add them to the system packages in the sling.properties file:
sling.system.packages.atg_jsp = javax.servlet.jsp;javax.servlet.jsp.el; \
javax.servlet.jsp.resources;javax.servlet.jsp.tagext;version=2.1.0
